PATENT JOSEPH O. GASKILL, OF OSW'EGO, NEW YORK, ASSIGNOR TO AMES IRON WORKS, OF OSl/VEGO, NEW YORK, A CORPORATION OF NEW YORK.

OIL ANDv WATER SEPARATOR.

SPECIFICATION forming part of Letters Patent N0. 774,57 7, dated November 8, 1904.

Application iled March 23, 1904.

To all whom, it muy con/cern:

Be it known that I, JOSEPH O. GASKILL, a citizen of the United States, residing at Oswego, in the county of Oswego and State of New York, have invented certain new and useful Improvements in Oil and Tater Separators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to oil and water separators; .and it has for its object to provide a simple, durable, and comparatively inexpensive separator; and it consists of the parts and combinations of parts hereinafter described and claimed.

In the accompanying drawings, forming a part of this specification, Figure l is a vertical section of my impropved oiland water separator; Fig. 2, an end view of the same; Fig. 3, a vertical section of a modified form of my invention; Fig. 4, an end View of the same, and Fig. 5 a vertical section of another modification of my invention.

Similar letters refer to similar parts throughout all the views.

Referring more particularly to Fig. l of the drawings, A represents a tank or vessel, preferably rectangular in shape, having a closed topand bottom and formed or provided with the ilaring iiange c at its top to form a hopper or receiving-chamber c for the mixed oil and water. From the lower or under side of the top of the tank or vessel a partition l extends vertically downward for a part of its length and then incliningly toward one side of the tank, as at (Z3, and terminates at a point slightly above the bottom of the tank. A partition {Z/ also extends from the under side of the top of the tank vertically downward parallel to and at a short distance from the partition Z and terminates at a point vabove the end of thestraight or unslanted part of the partition d, so as to provide a conductingchamber B between said partitions, which communicates at its upper end with the receivingchamber a through a slot or oblong opening d, formed in the top of the tank. By means of a Serial No. 199,596. (No model.)

short vertical partition cl2 and a transverse par- 5 O tition di, extending partly across the tank from the partition d, the conducting-chamberB is extended upwardly on itself and provides a discharge-chamber O, which opens into a separating-chamber D. The separating-chamber D is formed by the partitions zdf and the contiguous wall of the tank, said separatingchamber D being provided with an outletopening e near its top. E is a vertical intermediate chamber formed by the partition d 6o and a partition f, the latter extending from the bottom of the tank or vessel to a point near its top, but terminating below the outlet-opening e of the separating-chamber D. The partition f andl the adjacent wall of the tank or vessel form an overflow-chamber F` which has communication with intermediate chamber E over the top of the partition f. 'An outletopening g is provided for the overflow-chamber F near its bottom. H is a tapped or plug 7o opening formed in the bottom of the tank, whereby it may be cleansed of sediment.

This separator is designed, primarily, for the treatment of lubricating-oils, such as drippings from the bearings of steam-engines and machinery generally, so as to separate particles of foreign substances from the oil, and thus enable it'to be again used as a lubricant, and the form above described presents a convenient and preferred embodiment of my invention; but I do not desire to be restricted to such form, as it is obvious good results may be obtained from modied constructions without departing from the spirit of my invention, and in Figs. 3 and 4: and 5 I have shown 8 5 structural modifications which also embody my invention, as will be now described.

Referring to Figs. 3 and 4, AA represents the tank, and c the receiving-chamber, the latter having communication throughr an oblong opening c2 with a conducting-chamber B',

formed by the adjacent wall of the tank, and a partition D2,extending from the top of the tank downwardly and terminating at a point above a transverse partition D3 from the wall of the 95 tank, which connects with a short vertical extension D4, which extends upwardly in said tank parallel with the partition D2 and forms acontinuation of the conducting-chamber B and provides a discharge-chamber C, which opens upwardly into a separating-chamber D. The separating-chamber D is formed by the partitions D2D2 and the wall of the tank at one side and a partition E, which extends from near the bottom of the tank to a point above the outlet e ot' the separating-chamber D', near the top thereof, and said partition E, with a partition F, forming an intermediate chamber E2, which communicates with the separating-chamber D through the passage-way under the partition E and also has communication at its top over the partition F with an overliow-chamber F2, formed by said partition F and the contiguous wall of the tank. The partition F extends from the bottom of the tank to a point near the top thereof below the outlet-opening of the separatingchamber D, and an outlet-opening g is provided at or near the bottom of the overilowchamber F2.

In Fig. 5 is shown another form of my invention, in which A represents the tank, which may be partly open at its top, as at A2, and having the hopper-chamber a2 at one side thereof. The tank A is preferably cylindrical in shape, and the hopper-chamber communicates through an opening therein with a conducting-chamber B2, formed by a partition C2, extending downwardly from the top of the tank and the adjacent wall of the tank, the bottom of said conducting-chamber B2 being formed by atransverse partition C3 from the wall of the tank, which connects with a short vertical partition Ci, so as to provide a continuation of the conducting-chamber B2 and formingadischarge-chamber which opens upwardly into a separating-chamber E", formed by the wall of the tank and a cylindrical partition F2, which extends downwardly from the top of the tank to a point near the bottom thereof and is connected to a central tube G, which provides an intermediate chamber H, which extends upwardly from the bottom of the tank to a point near its top, but terminating below the plane of the outlet-opening e. The separatingchamber E3 has communication with the intermediate chamber H, formed by the partition F3 and the tube Gr, through the openings /L at the bottom of said intermediate chamber, and the intermediate chamber H has communication with the overflow-chamber H2, the wall of which is formed by the tube G, through the upper open end of said tube. An outlet-opening g is provided at the bottom of the overflow-chamber H2, and

tapped or plug opening H3 is provided at the bottom of the separating-chamber E2 to provide for the removal of sediment or the cleansing of the tank.

In operation the oil and water is supplied to the hopper-chamber and passes therefrom to the conducting and discharge chamber, from which it is discharged upwardly into the separating-chamber. The oil being the lighter rises to" the top of the water, and as the supply to the hopper continues the tank fills to the outlet-opening and the oil overflows therethrough. The water passes from the separating-chamber through the passageway therefor to the intermediate chamber and rises therein until it overflows into the overflow-chamber and escapes therefrom through the outlet thereof. This operation continues as long as the supply of oil and water is maintained.

It will be observed that the oil and water passes from the hopper in sheet form or in a thin flat column and is delivered to the separating or oil-discharging chamber in an upward directionand in a thin sheet, thus facilitating the separation of the oil and water.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

An oil and water separating tank constructed with a top having an opening and a flange providing a receiving-chamber, a transverse partition extending partly across the tank having an upward vertical extension, a depending partition located between the opening and the upward .vertical extension and extending downward to a position adjacent to the transverse partition and providing a vertical conducting-chamber on one side of the depending partition, a transverse passage beneath the lower end thereof and a short vertical discharge-chamber parallel with the conducting-chamber on the other side of the depending partition, a separating-chamber with which the discharge-chamber communicates having an oil-outlet at its upper end, an intermediate chamber with which the latter communicates at the lower end, an overflowchamber with which the intermediate chamber communicates at a lower level than the oiloutlet, and an outlet to the overflow-chamber.

In testimony whereofI aix my signature in presence of two witnesses.

JOSEPH C. GASKILL. Witnesses:
